What we do is create a "staging server" where we post the mobile site in a directory.
Tell the client to go look at his desktop website on his smartphone. (email the link if you like to make it easier).
In the same email, give the url of the mobile site created above to the client and ask them to look at the site on their smartphone.
Easy and effective.
